CCDC169-SOHLH2 (HGNC:38866): (CCDC169-SOHLH2 readthrough) This locus represents naturally occurring read-through transcription between the neighboring C13orf38 (chromosome 13 open reading frame 38) and SOHLH2 (spermatogenesis and oogenesis specific basic helix-loop-helix 2) genes. The read-through transcript encodes a fusion protein that shares sequence identity with the products of each individual gene. [provided by RefSeq, Nov 2010]

The c.104T>C (p.I35T) alteration is located in exon 2 (coding exon 2) of the CCDC169 gene. This alteration results from a T to C substitution at nucleotide position 104, causing the isoleucine (I) at amino acid position 35 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
